4.3.3.2 Redirect

The ICMP Redirect message is generated to inform a local host that it
should use a different next hop router for certain traffic.

Contrary to [INTRO:2], a router MAY ignore ICMP Redirects when
choosing a path for a packet originated by the router if the router
is running a routing protocol or if forwarding is enabled on the
router and on the interface over which the packet is being sent.
